Adult T-cell lymphoma/leukemia (HTLV-1-assoc), in remission

This code signifies a diagnosis of Adult T-cell lymphoma/leukemia (ATLL) that is currently in a state of remission. ATLL is an aggressive malignancy of mature T-lymphocytes, strongly associated with human T-lymphotropic virus type 1 (HTLV-1) infection. Remission indicates that the signs and symptoms of the disease have significantly decreased or disappeared.

Apply this code when documentation explicitly states that a patient with a history of HTLV-1-associated ATLL is currently in remission. This typically follows successful treatment, such as chemotherapy or stem cell transplant, and ongoing monitoring confirms the absence of active disease. Use this code for follow-up encounters where the patient's ATLL is not active.

• Ensure documentation clearly specifies "remission" for HTLV-1-associated ATLL.
• Do not use this code if the patient has active disease or is in an unspecified state.
• Consider sequencing this code after any codes for current treatment or complications, if applicable.
